Pain tolerance and threshold in suicide attempters: A systematic review and meta-analysis.

It has been hypothesized that individuals less sensitive to pain could be at higher risk of suicide. However, data on pain sensitivity in suicide attempters (SA) obtained using experimental procedures are heterogeneous. The aim of this systematic review and meta-analysis was to investigate and compare pain tolerance and threshold in SA (patients with lifetime history of suicide attempt), non-attempters (psychiatric controls, PC), and healthy controls (HC). A random effects meta-analysis was used to estimate the standardized mean differences using data from 16 studies that compared physical pain tolerance and threshold in SA and PC or HC. Pain tolerance and threshold were not significantly different in SA and PC. However, pain tolerance, but not threshold, was higher in SA than HC. Our findings do not support the hypothesis of an altered pain perception related as a trait for suicidal vulnerability, but rather suggest altered pain perception related to psychiatric vulnerability.

Integrating Psychiatric Services in the Emergency Room to Improve Patient Care by Using Quality Improvement Methods.

ABSTRACT: Prolonged length of stay in emergency departments (EDs) for patients with a psychiatric chief complaint is a widespread problem. Prolonged stays can lead to adverse outcomes and poor quality of care. We sought to improve quality of care for patients in the medical ED who needed psychiatric care. To identify the areas of weakness, we queried the ED staff via an online survey about the perception of the challenges working with our Comprehensive Psychiatric Emergency Program (CPEP), which is located adjacent to and works closely with the medical ED providing psychiatric consultation. We identified several action steps and used the Plan-Do-Study-Act methodology for implementation. We reported a reduction in time to complete consultations and improved communication between CPEP and the medical ED staff.

Low global frontal brain activity is associated with non-planned or impulsive suicide attempts. A preliminary study.

BACKGROUND: Suicide prevention is limited by the frequent non-planned or impulsive nature of suicidal behavior. For instance, 25-62 % of suicide attempts, occur within 30 min of the onset of suicidal ideation. We aimed to examine frontal brain activity in depressed patients following a suicide attempt and its relationship with the duration of the suicidal process. METHODS: We recruited 35 adult patients within three days of a suicide attempt of at least moderate lethality. Duration of the suicidal process was recorded in a semi-structured interview, including suicide contemplation (time from onset of suicidal ideation to decision to kill oneself) and suicide action intervals (time from the decision to kill oneself to suicide attempt). Resting state EEG data from AF7, AF8, TP9 and TP10 leads was collected with a portable MUSE 2 headband system. The average frequency values throughout a 5-minute portable EEG recording were extracted for delta (1-4 Hz), theta (4-8 Hz), alpha (8-13 Hz), and beta (13-30 Hz) waves. RESULTS: Delta (r = 0.450, p = 0.021) and theta power (r = 0.395, p = 0.044) were positively correlated with the duration of the suicide action interval. There were no significant correlations of the suicide contemplation interval with clinical or EEG measures. Patients with suicide action interval shorter than 30 min showed lower delta power (U = 113, p = 0.049) compared with those with longer duration. CONCLUSIONS: Lower theta and delta activity may reflect hindered cognitive control and inhibition in impulsive suicide attempters. Portable EEG may provide a valuable tool for clinical research and in the management of acutely suicidal patients.

The Use and Safety of Leave From an Acute Inpatient Psychiatry Unit: A Retrospective Review of Pass Outcomes for 4 Years.

ABSTRACT: Leave passes provide authorized leave for hospitalized patients from a psychiatric inpatient unit. Although providing day passes was once a relatively common practice, there are relatively few data describing their safety and efficacy. This descriptive study examines the use of leave passes in an adult inpatient unit at a university hospital between 2017 and 2021, with attention to reasons for granting the day pass, duration, and outcome of the pass. During the study period, 10 patients with primary psychotic or mood disorders received 12 passes for housing coordination, COVID-19 vaccination, or major family events. There were no fatalities or abscondments. One patient experienced severe agitation and engaged in nonsuicidal self-injurious behavior. A second patient showed mild, redirectable psychomotor agitation upon return to the unit. The remaining 10 passes were uneventful. Our findings support the view that patients with diverse diagnoses can safely be provided leave from an inpatient setting with adequate planning and support, yielding a low incidence of adverse events.

Characteristics of suicide attempts associated with lethality and method: A latent class analysis of the Military Suicide Research Consortium.

While suicide prevention is a national priority, particularly among service members and veterans (SMVs), understanding of suicide-related outcomes remains poor. Person-centered approaches (e.g., latent class analysis) have promise to identify unique risk profiles and subgroups in the larger population. The current study identified latent subgroups characterized by prior self-directed violence history and proximal risk factors for suicide among suicide attempt survivors, and compared subgroups on demographics and most-lethal attempt characteristics. Participants included civilians and SMVs reporting lifetime suicide attempt(s) (n = 2643) from the Military Suicide Research Consortium. Two classes emerged from Common Data Elements: suicide attempt and non-suicidal self-injury frequency, suicide attempt method, perceived likelihood of future suicide, suicide disclosure, suicide intent, and perceived and actual lethality of attempt. A Higher-Risk History class was characterized by greater intent to die, certainty about attempt fatality and method lethality, belief injury would be medically unfixable, and likelihood of prior non-suicidal self-injury. A Lower-Risk History class was characterized by greater ambivalence toward death and methods. Higher-Risk class members were more likely to be male, older, SMVs, have less formal education, use firearms as most-lethal attempt method, and require a higher degree of medical attention. Lower-Risk class members were more likely to be female, civilian, use cutting as most-lethal attempt method, and require less medical attention for attempts. Findings have implications for risk assessments and highlight the importance of subjective perceptions about suicidal behavior. Further investigation of real-time individual-level is necessary, especially for SMVs who may be at greatest risk for potentially lethal suicidal behavior.

The Experience of Pain is Strongly Associated With Poor Sleep Quality and Increased Risk for Suicide.

OBJECTIVE: Effective suicide prevention is hindered by a limited understanding of the neurobiology leading to suicide. We aimed to examine the association between changes in the experience of pain and disturbances in sleep quantity and quality in patients with elevated risk for suicide. METHODS: Three groups of adult depressed individuals, including patients following a recent suicide attempt (n = 79), patients experiencing current suicidal ideation (n = 131), and patients experiencing depression but no suicidal ideation or behavior in at least 6 months (n = 51), were examined in a case-control study for sleep quantity and quality, physical and psychological pain, pressure pain threshold, suicidal ideation, and recent suicidal behavior. RESULTS: Sleep quality, physical and psychological pain were positively associated with suicidal ideation severity. In both cases in which sleep quality was added to a model with either physical or psychological pain, physical or psychological pain became more significantly associated with suicidal ideation severity. Pressure pain threshold was elevated in patients suffering from any type of insomnia. There was no significant association between pressure pain threshold and suicidal ideation severity. CONCLUSIONS: The impact of these findings lies in the identification of both psychological and physical pain, and sleep quality as potential biological mechanisms underlying suicidal risk. HIGHLIGHTSWe assessed the association between pain and sleep quality in suicidal patients.Sleep quality, physical and psychological pain were associated with suicide risk.Pain perception may mediate the progression to suicidal behavior.

Synergistic effect of chronic pain and nonsuicidal self-harm on pain sensitivity.

Abnormalities in pain processing have been observed in patients with chronic pain conditions and in individuals who engage in self-harm, specifically nonsuicidal self-injurious behaviors (NSSI). Both increased and decreased pain sensitivity have been described in chronic pain patients, while decreased pain sensitivity is consistently observed in individuals with NSSI. The objective of the study was to identify the differential effects of chronic pain and NSSI on experimental pain sensitivity, specifically pressure pain threshold, in depressed patients. Moreover, the role that hopelessness may play between depression severity and pain sensitivity was also examined. Depressed patients with and without chronic pain, and with and without lifetime self-harm behaviors were analyzed into four groups. Group 1 (N = 42) included depressed patients with both Chronic pain ( +) and Self-harm ( +), Group 2 (N = 53) included depressed patients with Chronic pain ( +) but no Self-harm (-), Group 3 (N = 64) included depressed patients without Chronic pain (-), but Self-harm ( +), and Group 4 (N = 81) included depressed patients with neither Chronic pain (-) nor Self-harm (-). Healthy controls (N = 45) were also recruited from the community. Depressed patients with both Chronic pain ( +) and Self-harm ( +) reported higher pressure pain threshold measures when compared with the other groups. Mediation analysis indicated that hopelessness mediates the relationship between depression severity and pressure pain threshold. Our findings suggest that a multiprong approach including adequate mental health services and pain control for depressed patients with comorbid chronic pain and nonsuicidal self-harm is needed to yield effective outcomes.

Altered physical pain processing in different psychiatric conditions.

Several reports indicate either increased or decreased pain sensitivity associated with psychiatric disorders. Chronic pain is highly prevalent in many of these conditions. We reviewed the literature regarding experimental pain sensitivity in patients with major depression, bipolar disorder, posttraumatic stress disorder (PTSD), generalized anxiety disorder, panic disorder, obsessive-compulsive disorder and schizophrenia. Electronic searches were performed to identify studies comparing experimental pain in patients with these conditions and controls. Across 31 depression studies, reduced pain threshold was noted except for ischemic stimuli, where increased pain tolerance and elevated sensitivity to ischemic pain was observed. A more pervasive pattern of low pain sensitivity was found across 20 schizophrenia studies. The majority of PTSD studies (n = 20) showed no significant differences compared with controls. The limited number of bipolar disorder (n = 4) and anxiety (n = 9) studies precluded identification of clear trends. Wide data variability was observed. Awareness of psychiatric patients' pain perception abnormalities is needed for active screening and addressing physical comorbidities, in order to enhance quality of life, life expectancy and mental health.

Orthopaedic Surgeon Mental Health During the COVID-19 Pandemic.

Introduction: This study compares rates of depression, suicidal ideation, and burnout among resident/fellow and attending physicians in orthopaedic surgery to other specialties during height/end of the first wave of the coronavirus disease 2019 (COVID-19) pandemic at our institution. Main outcomes and measures included suicidal ideation, Patient Health Questionnaire for Depression (PHQ-9) scores for depression, and 2 single-item measures for emotional exhaustion and depersonalization. This study provides valuable information regarding orthopaedic surgeon mental health during world crises. Methods: This is a cross-sectional survey-based study of resident, fellow, and attending physicians from 26 specialties during and after the first wave of the COVID-19 pandemic at our institution from April 24, 2020 to May 15, 2020. The survey contained 22 items. This includes consent, demographics and general data, 2 single-item questions of emotional exhaustion and depersonalization, and the PHQ-9. Subjects were eligible if they were a resident/fellow or attending physician at our institution. Results: The response rate for the study was 16.31%. Across all specialties rates were 6.2% depression, 19.6% burnout, and 6.6% suicidal ideation. The results for orthopaedic surgeons are as follows: 0% tentative diagnosis of depression, 3.8% suicidal ideation, and 4% burnout. Anesthesiology had the highest rate of depression (14.3%). Internal medicine and other non-surgical specialties had the highest rate of suicidal ideation (10.2%). Orthopaedic surgeons were significantly more likely to achieve work-life balance and experience less burnout than anesthesiologists and pediatricians. Discussion: Depression, suicidal ideation, and burnout continue to affect physicians across all specialties. These issues are amplified in light of crisis. Job satisfaction and rigorous training may be protective factors that allow orthopaedic surgeons to adapt to novel clinical settings under stress when compared to anesthesiologists and pediatricians. Resilience training and stress management strategies should continue to be investigated to better prepare physicians for world crises.

Depression, Suicidal Thoughts, and Burnout Among Physicians During the COVID-19 Pandemic: a Survey-Based Cross-Sectional Study.

OBJECTIVES: Frontline workers have been a bulwark in the fight against COVID-19, while being subject to major unexpected stressors. These include conflicting news, evolving guidelines, perceived inadequate personal protective equipment, overflow of patients with rising death counts, absence of disaster training, and limitations in the implementation of social distancing. This study investigates the incidence and associated factors of depression, suicidal thoughts, and burnout among physicians during the COVID-19 pandemic. METHODS: In a cross-sectional survey-based study of resident, fellow, and attending physicians from a tertiary university hospital during the height of the COVID-19 pandemic in New York from April 24 to May 15, 2020, demographics and practice specialty, attending vs. resident/fellow status, call frequency, emotional exhaustion, depersonalization, and depression severity were examined. RESULTS: Two hundred twenty-five subjects completed the survey (response rate of 16.3%), with rates of 6.2% depression, 6.6% suicidal ideation, and 19.6% burnout. Depression, suicidal ideation, and burnout were all associated with history of prior depression/anxiety and frequency of on call. Suicidal ideation and burnout were also associated with younger age. There was no difference in rates of depression, suicidal ideation, or burnout between attending and resident physicians. Female physicians reported less work-life balance and more burnout. CONCLUSIONS: These findings highlight the importance of considering physician mental health during times of peak stress, such as natural or man-made disasters. The prominence of premorbid depression/anxiety as a relevant factor underscores the need to further understand physician mental health and provide early screening and treatment.

Examination of physician factors influencing psychiatric assessment of acutely suicidal patients.

Suicide risk assessment is a subjective process and remains a clinical challenge in psychiatry. We aimed to examine physicians' characteristics that influence management of acutely suicidal patients. In a cross-sectional design, we performed an anonymous internet survey of psychiatry residents and attendings from four academic centers. Gender, years of experience, practice setting, prior patient suicide, and personal exposure to suicide were characterized. Participants were presented with three clinical vignettes and asked to rate suicide risk and clinical disposition. The relationship between responses to the vignettes and physician characteristics were examined with generalized linear models. Fifty-four residents and 49 attendings completed the survey. Four (7%) residents and 24 (49%) attendings had patients die by suicide, whereas 32 (59%) and 36 (74%), respectively, knew somebody outside their practice who died by suicide. Among residents, lower rating of acute suicide risk was associated with prior exposure to non-patient suicide. Less hospitalization chosen by attendings was associated with greater perceived difficulty of suicide risk assessment. In the combined resident and attending sample, less proneness to hospitalize was associated with number of previous patients die by suicide and with outpatient practice. Our results suggest that previous exposure to suicide is associated with more risk-averse management.

Examination of structural brain changes in recent suicidal behavior.

We aimed to identify brain structural changes in cortical and subcortical regions linked to recent suicidal behavior. We performed secondary analyses of structural MRI data of two independent studies, namely the Establishing Moderators/Biosignatures of Antidepressant Response - Clinical Care (EMBARC) study and a Little Rock study on acute suicidal behavior. Study 1 (EMBARC, N = 187), compared individuals with remote suicide attempts (Remote-SA), individuals with lifetime suicide ideation but no attempts (Lifetime-SI only), and depressed individuals without lifetime suicide ideation or attempts (non-suicidal depressed). Study 2 (Little Rock data, N = 34) included patients recently hospitalized for suicide ideation or attempt constituted by: patients who recently attempted suicide (Recent-SA), individuals with remote suicide attempts (Remote-SA), and Lifetime-SI only. Study 3 combined the EMBARC and Little Rock datasets including Recent-SA, Remote-SA, Lifetime-SI only and non-suicidal depressed individuals. In Study 1 and Study 2, no significant differences were observed between groups. In Study 3, significantly lower middle temporal gyrus thickness, insular surface area, and thalamic volume and higher volume in the nucleus accumbens were observed in Recent-SA. This pattern of structural abnormalities may underlie pain and emotion dysregulation, which have been linked to the transition from suicidal thoughts to action.

COVID-19-Induced Psychosis and Suicidal Behavior: Case Report.

The COVID-19 pandemic is associated with different types of stressors: fear of infection, financial burden, and social isolation. Additionally, COVID-19 infection seems to increase the risk for neuropsychiatric symptoms including psychosis. We present a case of a 52-year-old male with no previous psychiatric history who developed severe paranoia leading to a suicide attempt. He was successfully treated with a combination of milieu treatment, pharmacotherapy, and electroconvulsive therapy. We add to the nascent literature that COVID-19, as other coronaviruses, can increase the risk for severe psychosis and suicidal behavior.

Slower perception of time in depressed and suicidal patients.

Effective suicide prevention is hindered by a limited understanding of the natural progression and neurobiology of the suicidal process. Our objective was to characterize the duration of the suicidal process and its relation to possible determinants: time judgment and cognitive impulsivity. In four groups of adults of both sexes including recent suicide attempters (n = 57), suicidal ideators (n = 131), non-suicidal depressed controls (n = 51) and healthy controls (n = 48) we examined time estimation and production, impulsivity and other cognitive variables. Duration of the suicidal process was recorded in suicide attempters. The suicide process duration, suicide contemplation and action intervals, had a bimodal distribution, ∼40% of attempters took less than 5 min from decision to attempt. Time slowing correlated negatively with the suicidal action interval (time from the decision to kill oneself to suicide attempt) (p = .003). Individuals with suicide contemplation interval shorter than three hours showed increased time slowing, measured as shorter time production at 35 s (p = .011) and 43 s (p = .036). Delay discounting for rewards correlated with time estimation at 25 min (p = .02) and 90 s (p = .01). Time slowing correlated positively with suicidal ideation severity, independently of depression severity (p < .001). Perception of time slowing may influence both the intensity and the duration of the suicidal process. Time slowing may initially be triggered by intense psychological pain, then worsen the perception of inescapability in suicidal patients.

Neuromodulation for Apathy in Alzheimer's Disease: A Double-Blind, Randomized, Sham-Controlled Pilot Study.

BACKGROUND: Apathy, a profound loss of motivation, initiation, and goal directed cognition, is a common comorbidity of Alzheimer's disease (AD). The presence of apathy is associated with rapid progression of AD, long-term impairment, disability, and higher mortality. Pharmacological treatments of apathy are limited. OBJECTIVE: The primary objective was to evaluate the efficacy of repetitive transcranial magnetic stimulation (rTMS) for apathy in AD. METHODS: A randomized, double-blind, parallel-arm, sham-controlled pilot study was conducted in subjects with AD and apathy (N = 20). Subjects were randomized to rTMS or sham treatment (5 days/week) for four weeks. Primary outcome, apathy evaluation scale-clinician version (AES-C), and secondary outcome measures, modified-Mini Mental State Examination (3MS), instrumental activities of daily living (IADL), and clinical global impression (CGI), were assessed at baseline and four weeks. Follow-up visits were conducted at 8 and 12 weeks to test the durability of effects of intervention. RESULTS: Mean age was 77.3 (±7.2) years, 80% were Caucasians and 10% were females. After adjusting for baseline, there was a significantly greater improvement in the AES-C with rTMS compared to sham treatment (-10.1 (-15.9 to -4.3); t (16) â€Š= -3.69; p = 0.002) at 4 weeks. There was also significantly greater improvement in 3MS (6.9 (1.7 to 12.0); t (15) â€Š= 2.85; p = 0.012), IADL (3.4 (1.0 to 5.9); χ21 = 7.72; p = 0.006), CGI-S (1.4 (0.5 to 2.3), t (16) â€Š= 3.29; p = 0.005), and CGI-I (-2.56 (-3.5 to -1.6), t (17) â€Š= -5.72; p < 0.001) for rTMS compared to the sham at 4 weeks. The effects of rTMS were durable at 12 weeks. CONCLUSION: rTMS may be safely used in subjects with AD and may improve apathy, function, and some aspects of cognition.

Buprenorphine use for pain and suicidal ideation in severely suicidal patients.

OBJECTIVE: Chronic pain is frequently comorbid with opioid abuse and severe depression, a combination that greatly compounds suicide risk. In addition to the therapeutic value of buprenorphine in addiction and analgesia, growing evidence suggests potential use as an antidepressant. Data supporting buprenorphine antisuicidal properties are scarce. We aim to contribute to the discussion of buprenorphine antisuicidal potential in patients with significant psychiatric and medical comorbidity. METHODS: We performed a chart review of suicidal adult depressed patients with comorbid chronic pain and opioid use disorder who received off-label buprenorphine in outpatient and inpatient settings in a university hospital between 2013 and 2016. RESULTS: Four of the patients had an early positive response. However, only three continue to adhere to treatment for six months or longer. CONCLUSIONS: More severe opioid use disorder seems to more negatively influence clinical outcome, independently of cluster b personality traits. Identification of patients who could benefit from buprenorphine will require further studies.
